Mother immigrated to the US from England about 1892.
Father's ancestors have been in US since Colonial times; German Palatine roots.

Their ethnic ancestry appears to be 100%
Anglo-Saxon and is about evenly split between English, Icelandic, Dutch, and
German. Though they lived in West Prussia for several generations, their
branch of Mennonites were mostly Dutch in origin. Probably no more than 5
percent of their ancestry is from what was once Prussia. The majority of
their German ancestry is from further south (Rheinland-Pfalz, Alsace,
Switzerland).

Immigrants: One grandparent (1950s), two
great-grandparents (1914-22), seven great-great-grandparents (1880s-1890s).
One branch in US since before Revolution.
